This invention relates to improvements in statistical card machines andhas particular reference to a combined punch and verifier, thisapplication being a division of the co-pending application of CliffordC. Leatherman and William Wockenfuss, Serial No. 141,428, filed January31, 1950. v

A feature of the invention is to provide an improved machine ofpractical construction wherein the operations of punching and verify-'ing cards are accomplished by the alternate use of punch and verifyingelements so arranged that'each is under the control of. the sameinstrumentalities.

"Another and more specific feature is to coaxially dispose the punch andverifying elements one within the other in such manner as toenable theoperation of the verifying element independently of the punch whenverifying a record card. The above and other features will appear moreclearly from the following detailed description when taken in connectionwith the accompanying drawings which illustrate a preferred embodimentof the inventive idea; but it is to be expressly understood that saiddrawingsare employed merely to facilitate the description of theinventi'on'as a whole and not to define the limits thereof, referencebeing had to the appended claims for this purpose.

In the drawings:

(01. lee-11s) shown, generauy; in Fig. 1'as c'omprisinga' base I5 over which" the main casing'lfi is supportedand 'prov'i'de'd with an intermediate forwardly a'n'd downwardlyinclined'section I1 upon which is'inounted the plate '18 havinglongitudinal guide strips l9bet'ween whicha record card is disposedwhile being punched or verified. Said card, wl ieriin position,-eictends beneath a housing arranged transversely of the plate [8' andlocated directlyabovea row of punches and verifying pins whichareoperated from beneath the card.

arrangement, including the inclination of the section l'lfiss'uch thatthe entire card, with the exception of that portion thereof directlybeneath thefhousin'g 20, will be clearly visible to theoper ato'r duringa punching or verifying operdirect1ybenea'th the lower end of theinclined housing 20 to receive chips which are punched from thecards.Above the rear top section of the casing it, a housing 26 encloses andis attached to'a movable portion of an automatic skip mechanism,generally indicated at 21 and fully disclosed and claimed in the abovementioned parent application, and said movable porti'on is secured andactually forms part of the movable card carriage generally indicated at28. Thus, 'by'means of the finger piece 29 attached to the casing 26,the portion" 21 of the skip mechanism and the card carriage may be movedlongitudinally to the right from' the'position shown in Fig. 1 to thestarting position wherein the punches and'verifying pins under thehousing '20 will be in linewith thefirst column of'a new "record cardinserted between the guides I9 andthe abutments 30 extending forwardlyfrom the card carriage (Fig: 2) and which project through a slot 31formed in the plate l8 for engagement with the ends or the card toproperly center and retain the'same for punching and verifyingoperations as the carriage is moved along, step by step. A'switch 32mounted on one side of the casing 16 is" utilized to cut intheelectrical circuits of Fig. 12 when. shifting control ofthemachine-fr'om punching to verifying operations, and vice versa.

Card carriage and its escapement The card carriage 28 is composed of theupper and lower longitudinal rails 33 and 34 (see Fig. connected by thetransverse end pieces 35, and said rail carry the grooved rollers 36which engage and roll along the upper and lower beveled edges of thestationary guide plate 31. The upper rail 33 has secured thereto theforwardly extending arms 38 (Fig. 2) which carry the card abutments 30and which extend through and are movable in the longitudinal slots 39formed in a rear plate 40 that supports the guide plate 31 and alsocooperates with the parallelfront plate 4| to support the punches andverifying pins to be hereinafter described.

A portion of the bottom edge of the lower rail 34 is formed with theteeth 42 constituting a part of the carriage escapement, and to the rearface of said rail there is secured a plate 43 provided with a rack 44engaged by a spur gear 45. Said gear driven from the spring motor,generally indicated at 46 (Fig. 3), to advance the carriage inaccordance with the operation of the various keys of the keyboard, andthe advance of the carriage is controlled by the escapement mechanismwhich includes the two pawls 47 and 48 (Fig. 6) that alternately engagewith the teeth 42 to control such advance. The pawl 41 and the bellcrank 49 to which it is fixedly connected are pivotally supported,intermediate their ends, on the stub shaft 50, and a spring 5| attachedto one end of the bell crank normally maintains the latter and said pawlin the position shown in Fig. 6. However, when the pawl 41 is eitheractuated by the punch solenoid. 52 (Fig. 3) or the bell crank 49 isrocked by the space solenoid 53 to which it is connected, said pawl willengage with one of the teeth 42. In either event, the rocking of thebell crank 49, one end of which engages a pin 54 on the arm 55, causesthe latter to be rocked counterclockwise with the result that its bentend 55 resting on the upper edge of the pawl 48 turns said pawl aboutits pivot 51 to disengage it from the tooth with which it has beenengaged while holding the carriage against advancement. Upon suchdisengagement, a spring 58 advances said pawl 48, which is looselymounted on its pivot, a slight distance suificient for it to engage thenext succeeding tooth 42 when the pawl 47 is restored by thede-energization of the punch solenoid and consequent action of thespring 5| thus eifecting a single step movement of the carriage.

When spacing, either during punching or veritying operations, the spacesolenoid 53 is controlled directly from the space key 59 (Figs. 1 and 7)and upon energization of said solenoid, it rocks the bell crank 49 andalso the pawl 41 resulting, as previously described, in the advancementof the carriage one step.

A full release of the carriage is accomplished by the operation ofrelease key 60 electrically connected directly to the release solenoid6| which, when energized, rocks the lever 62 to depress its free endthat has the shoulder 53 formed thereon. A spring-biased latch 64 thenacts to engage over said shoulder so that said lever 62 will be held ina depressed position until the carriage is fully released. Operation ofsaid lever causes its end adjacent said shoulder 63 to engage theextension 55 of an escapement control member in th form of the slide 65and depress the latter. This slide is a part of the stationary portionI21 of the skip control mechanism fully described in said co-pendingapplica tion, and its lowermost extremity is bent laterally to form aprojection 51 that overlies and engages the bent end 53 of the pivotedarm 55 so that when the slide is depressed said arm will be rocked todisengage the pawl 48 from the teeth 42. Under control of the springmotor 46, the carriage now will move uninterruptedly to its full releaseposition. Depression of the slide 66 has other functions in relation tothe automatic skip mechanism 21 which need not be described herein. Onreaching the full release position of the carriage, a release member 68(Fig. 6) adjustably secured to said carriage contacts the pivoted latch64 to disengage it from the shoulder 63, thus permitting lever 62 of thesolenoid 6| to restore and also allowing the slide 66 to return to itsnormally raised position. It may be noted that the skip key 69 on thekeyboard is also directly connected electrically to the skip solenoid 10so that closure of said key will energize said solenoid to rock its armI the free end of which will then engage the extension 65 of the slide66 to thereby depress the latter. Again, the slide 66 will eifectrelease of the pawl 48 so that the carriage will move freely toward itsrelease position. However, in this skip operation, the carriage willadvance only a predetermined distance under control of the skipmechanism 21.

The punches and verifying pins and operating mechanism therefor The rearand front plates 40, 4| of the machine form a support for the punchesand verifying pins 81, the constructions of which are best shown in Fig.5. A single row of these elements extends transversely between saidplates 40, 4| which carry the guide block 88 for said elements. Saidpunches cooperate with a die plate 89 to perforate a card as it isadvanced between said plate and the upper ends of the punches.

According to one of the features of the invention, each punch and itsassociated verifying pin are co-axially arranged with the pin extendingthrough the punch and having independent or relative movement withrespect to the latter during a verifying operation in which the punchremains in its normal or lower position and the pin is raised to eitherpass through a perforation in the record card being verified or engagethe under surface of said card. When a perforation is sensed, thecarriage escapement operates to advance the card to the next column tobe verified, but if the card is engaged by the pin, the escapement failsto operate and the operator of the machine thereby becomes aware of anincorrect punching.

Each punch element and its verifying pin have associated therewith anactuator bar 90 (Figs. 3 and 4) which, in both punching and verifyingoperations, has an initial longitudinal movement imparted thereto by theenergization of an individual solenoid 9| under control of one of thekeys 22, said movement being effected by a bell crank 92 interconnectingthe solenoid plunger with its bar. In a punching operation, thislongitudinal movement of the bar 90 is employed to energize the punchsolenoid 52, in a manner to later appear, which then controls mechanismto impart upward or secondary movement to said bar to transmit a similarmotion to the punch 86 whose lower enlarged end rests upon the upperedge of said bar and that of a guide plate 93 secured to said bar andforming a guide for the verifying pin 81. When punching, the initiallonanem cgitudinahmovement of the baron ialsc resultsin 'the elevationof the pin 83 along with its ipunch but this obvious thatthisoperationof the'pin has-noeffect since it will passthrough-theperfora-tion inthe record card formed byithe-punc'h.-

When verifying, the initial longitudinal movement of the bar-90 is theonly actuation thereof that occurs since, in this instance, the punchsolenoid 52 will not be energized and theonly result of said movement ofthe bar will be to elevate the verifying pin independently and'relativeto its punch to sense Whether or not a perforation has been made in thecard being verified at the index point corresponding'to the operatedkey-'22.

Returning to the punched operation and by particular reference to Figs.2, 3 and 4, it will-be seen that the actuatorbars 90 allextend through acomb 94 located just to the right of the guide plates 93 on said bars:The latter then project through a Vertically guidedbail plate 95 commonto the bars 99 and cut out to receive the same, an edge of said platebeing; beveled at 96 to cooperate with the beveled edge of a shoulder 91on each of-said guide plates 93 when said bail plate is raised toelevate a punch. Said beveled edges also cooperate, when engaged, toprevent return of an actuator bar 90 upon de-energization of itssolenoid 9|. In. the normal position of Fig. 3, the beveled shoulders 9on all the guide plates 93 are out of vertical alignment with the edge96 of said'bail plate so. that any vertical movement oflthe latter willhave noeffect upon a bar. 95 and. its associatedpunch 8'6, butwhenanyone of the bars is advanced longitudinally,

to the position of Figure 4, by the energization ofits solenoid 9! thetwo mentionedbeveled edges will be brought. into alignment preparatoryto the secondary or. upward movement of saidbar under the influence ofthe punch solenoid 52. The. amount of movement of the bail plate 95, andconsequently of the punches 86,.may be regulated by an adjustment of theset screws 98 which engage the lower edge of said plate adjacent itsends, there being only one, of such set screws shown in the drawings.

With the switch .32 (Figs. 1 and 7) in the punching position, when oneof the keys 22 is struck its associated .bar 9! is initially movedlongitudinally to the left, as viewed in Fig. 3,

to turn, the arm 89 loosely mounted on the rock shaft "It to theposition of Fig. 4.;- lngconnection with a verifying operation,this-notion. of-v the arm-99 results in the elevation of theverif-yingpin along with itspunch. as previously men-- punch solenoid 52 whichthen energizes.

When verifying a record card which has been I punched, the switch 32 ismoved to the. dotted 'linegposition of Fig. 7,, thus disconnecting thepunch solenoid 52 from the operating circuit. Striking of one of thekeys 22 operates the associated actuator bar with the same result aspreviously described except that closure of the punch contacts I06 hasno effect because of the position ofthe switch 32 and therefore thepunch solenoid will not beenergized, and with the fur-.- therresult thatthe bar- 90 has only its initial the arm I2I.

,7 longitudinal movement imparted thereto. Operation of the arm 99 byits bar 90 swings an extension I20 (Fig. 4) of said arm upwardly to freeanother arm I2I pivoted on the shaft I for upward movement and thislatter movement is accomplished by a spring I22 connecting said arm I2Iwith the arm 99. Said arm I2I is connected to the lower end of theverifying pin 81 which is now raised independently of its associatedpunch to sense for a perforation in the card being verified. If there isa perforation in the card, the upper end of the pin will passtherethrough and the parts will assume the position of Fig. 4 in whichthe arm I2I will have elevated a restoring bail I23 common to all saidarms. Said bail is secured to the shaft I00 and, by being elevated, willrock the shaft and thus produce a swinging movement of the depending armI24 also secured to said shaft and this movement, which is against theaction of the return spring I25, will be suiiicient to close the spacecontacts I26 for the space solenoid 53 which then energizes. Solenoid 53now operates the bell crank 49 to initiate the operation of theescapement mechanism as previously described. Should the verifying pincontact a record card instead of passing through a perforation therein,the upward movement of said pin will be stopped, as will be the similarmovement of the arm I2I and the restoring bail I23 and, therefore, theswinging movement of the arm I24 will be insuiiicient to close the spacecontacts I20 with the result that the escapement mechanism will not beoperated to advance the card carriage. Con tinued movement of the arm 99after the pin 81 engages a card, will then be against the tension of thespring I22 and the extension I20 of said arm will disengage itself fromthe arm I21. At the conclusion of the upstroke of the verifying pin,either in th event that it passes through a perforation or contacts acard, the actuator bar 90 restores so as to return the arm 99 to itsnormal position and re-engage the extension I20 with At the same time,the spring I25 connected to the arm I24 then restores the latter tonormal and, in so doing, rocks the shaft I00 to depress the bail I23 toreturn the arm I2I to its lower position and thereby similarly restorethe verifying pin.
